报告没有别名的派生表。
<p>示例 (MySQL)：</p>
<pre><code>CREATE TABLE table1 (id INT, name VARCHAR(20), cats FLOAT);
CREATE TABLE table2 (id INT, age INTEGER);

SELECT id AS ID, name, cats, age
FROM (SELECT table1.id, name, cats, age
FROM table1
JOIN table2 ON table1.id = table2.id);</code></pre>
<p>根据 <a href="https://dev.mysql.com/doc/refman/8.0/en/derived-tables.html">dev.mysql.com 上的 Derived Tables</a>，别名是强制的。 您可以使用<b>引入别名</b>快速修复来添加别名。</p>
<p>在应用快速修复后：</p>
<pre><code>SELECT id AS ID, name, cats, age
FROM (SELECT table1.id, name, cats, age
FROM table1
JOIN table2 ON table1.id = table2.id);</code></pre>
